基于十二区间的模糊直接转矩控制的研究

为了解决传统直接转矩控制中转矩脉动过大，提出了利用基于十二区间的模糊直接转矩控制的方法。首先分析基于传统六区间直接转矩控制的问题，提出基于十二区间法的直接转矩控制，并且推理了十二区间法的矢量作用。其次根据电机高速时使用滞环时造成的开关频率过大的问题，提出使用模糊控制器来代替滞环的作用。最后使用Matlab／Simulink搭建基于十二区间的模糊直接转矩控制的系统，并证明此系统具有良好的性能。

Research on Direct Torque Control based on Twelve-Area

In order to solve the problem of big torque pulse in traditional direct torque control(DTC),the fuzzy DTC method based on twelve-area is presented.Firstly,the problem of the traditional six-area method was analyzed,and then the twelve-area method was proposed and vector action of it was derived.Due to the problem of over-high switch frequency resulted from high speed operation of motor,the fuzzy controller was presented instead of the hysteresis loop.At last,the fuzzy DTC system based on twelve-area was est...
